A container and closure in combination, said container comprising a base portion with an enclosed side wall extending upwardly from said base portion, a substantially cylindrical first neck portion having a substantially uniform outer surface along its entire length extending upwardly from a transition portion, said transition portion comprising a top wall extending radially inwardly to said first neck portion, said enclosed side wall comprising a perimeter substantially larger than the circumference of said first neck portion, said first neck portion being substantially centered above the enclosed side wall and transition portion, said container narrowing from said transition portion to said first neck portion, a second neck portion extending from said first neck portion, said second neck portion comprising an externally threaded annular sleeve, the outer surface of said externally threaded annular sleeve being spaced radially inwardly from said outer surface of said first neck portion so as to form an annular ledge between said first and second neck portions, said container being formed as a one piece unit; said closure comprising a sleeve having a substantially uniform and substantially cylindrical external surface along its entire length, the closure sleeve having an interior, the length of said interior having a midpoint, said closure sleeve having a central longitudinal axis, said closure sleeve further comprising a transverse dividing wall at the interior midpoint, said dividing wall positioned perpindicularly to said central longitudinal axis, said dividing wall separating the interior of the sleeve into two substantially identical bore portions, each bore portion being substantially identically internally threaded and threadably attachable to said second neck portion, said closure sleeve being bounded by opposed ends, said closure external surface having substantially the same diameter as said first neck portion, said closure sleeve and each internally threaded bore of the closure comprising a length such that when one of said internally threaded bores is secured to said externally threaded annular sleeve of said second neck portion of said container, said closure and said first neck portion presents a substantially cylindrical handle having a substantially uniform cross section except for any gap that may exist between said ledge and a respective end of said closure sleeve, the other of said internally threaded bores being provided for attachment in the same manner to a substantially identical container.
